Last night our mail was screwd up accidentally anyone sending mail to me would have received bouced messages. I see terry's ansewer to this mail and her refers to other answers if you send a response, please resend.. ESPECIALLY if you know how to get gdb in kernel debugging mode to show stacktraces from other processes. I want to hear from you! julian a recap on the problem: Take the following 3 processes: > > proc N, with a lock on file / (inode 2) > wchan of that inode, waitstring of "ufslk2" > is waiting for inode for /mnt in the root filesystem (inode M) > > proc N+1 with a lock on the inode M (/mnt in root filesystem) > is waiting for inode for / (inode 2) in the mounted filesystem /mnt > it is showing "uihget" as a waitstring. > > proc N+2 with a lock on inode 2 of the mnt filesystem (/ of that filesystem) > is waiting for the inode for / and is showing "ufslk2" as a waitstring. > > It is my suspicion that process N+2 may be trying to unmount /mnt P.S. Terry it is NOT running NFS.. NFS is not even loaded.
